The CodePlex team just shipped mailing list support for project discussions. Details are available at http://blogs.msdn.com/codeplex/archive/2008/07/23/codeplex-project-discussions-mailing-lists.aspx.
While we've had this mailing list for years, I've spoken to the CodePlex team and it should be possible to make the switch over to the CodePlex infrastructure. However, I wouldn't want to make a change like that without getting some feedback from the community at large.
If you've got a strong opinion about CodePlex mailing lists one way or another, please let me know.
